Fifa will soon be able to buy green electricity, produced by the Darling Wind Farm, for the World Cup. This wind energy can also be used to illuminate city landmarks like Table Mountain.

Mayoral committee member for utility services Clive Justus said the power generated by the wind farm equated to half of the Civic Centre's electricity consumption.

However, the city had agreed to buy the electricity so that the Darling Wind Farm project could be sustained. The council plans to get 10 percent of its energy from renewable sources by 2010, said Justus.

In terms of its agreement with the National Energy Regulator of SA, the premium the city has to pay for green electricity from Darling may not be spread across all electricity consumers. The premium, which is above what it would have otherwise bought from Eskom, must be recovered from "willing buyers".

The city will sell the benefits of this green electricity in the form of "Green Electricity Certificates". One certificate will be created for every net 1 kWh of electricity that is generated by the wind farm and bought by the city.

While some of the green certificates will be retained for the council's own use, they will also be sold to Fifa, the CTICC and public bidders at premium rates.

But mayoral committee member for finance Ian Neilson yesterday questioned the terms and conditions of the sale of the certificates.

These include a stipulation that the benefits of buying green certificates will be non-negotiable because of the lack of a nationally-recognised tradable electricity certificate system.

Brian Jones, of city electricity, said it was international best practice to trade in the rights to the benefits of green energy.

But Neilson said he wanted clarity on the terms of the certificate agreements.
